reference shame? warm suppm fiuppm-ted 1110011 the, frame marrying brake: shoes W2 has '1" I Nasal ggezus 32 and ed in unwind the direction of link 45 which is also loosely connedted to the in this manner the saw is fed into the work its lower end is formed with a crank ll and swingingly connected to the shaft 38 at o osite sides of the said crank 41 is a gui e mine 42- in one end of which is formed a guide sleeve 48 through which works a slide rod 44, the latter being loosely connected to a crank 41 and on the outer end of the said slide rod is is carried a saw blade 46 the same being outwardly tapered and is provided with sa-W teeth 47 opposite longitudinal edges thereof, the blade 45 being formed with a collar 48 fitting upon the slide rod 4M and carrying a set screw whereby the said collar 48 may be looked upon the slide rod so that the saw can he sustained in its adjusted position for cutting logs or for telling trees.

The guide frame 42 is adapted to swing upon the shaft 38 and to accomplish this there is connected to the said frame 1-2 the ends of a flexible cable 50, the said ends of the cable being connected at points opposite the axis of movement of the frame and this cable is Wound about the counter-shaft 31 near the lower end thereof so that on rotating' the latter in one direction it Will cause the swinging" of the frame 42 in one direction and on the turning of the counter-shaft 31 in the reverse direction the said frame will he swung in the opposite direction and during the cuttingoperation thereof.

Formed on the rocking frame 28 is an e tension forming a hearing in which is pivotally mounted a rocking lever 52, the same being loosely connected at one end to the countenshaft 31, so that upon movement of thelever 52, the said shaft may he raised or lowered for bringing the friction gears 32 and 33 alternately into engagement. with the friction pinion 34 for reversing the action of the saw. Stationarily fitted about the shaft 38 at the upper end thereof is a sleeve 53 which is held fast in the hearing of the frame 28 and loosely engaged with this sleeve is the loop terminal 5% of the other end of the rocking lever 52, the sleeve being formed with spaced vertically die posed openings in any one of which is adapted to engage a locking pin 56, the mat ter being controlled through the medium of a manually operated spring held latch device 57 which is supported upon a throw lever 58 thetsaln'e being connected to the'rocking le vel- Ligand being also engaged in a hearing '59itormed in the upper end of a throw lever 60;the latter being .ivotally connected to' the frame 10 and carrying a manually controlled spring held latch device 61 which is adapted to engage a toothed segment 62 formed on or mounted upon the said frame 10, the lever 58 being designed vto rock the lever 52 so as to shift the shaft 31 for bringmg the triction gears 32 and 33 into cng'agei gaged therewith as will be rea posit-ion by means of the latch device hereinafter described On adjusting the rocking frame 28 the angular disposition of the saw maybe-attained. On swinging the yoke 22 the same frame 28 can he raised or lowered with respectito the ground and 'n this manner tee saw can be brought ir proper Working position with respect to s Work to be cut thereby. The sprocllet Wheel 35 is locked and unlocked from the shaft through the medium. of a clutch 63 ch actuated through a hand lever (is so action of the saw he stopped and a at will. the engine being controlled i ordinary ivelldrnown manner. barren frame is formed with the n t dies 65 and also vr props or lees that the machine be wheeled and brought to rest in the same an ordinary wheelbarrow,

From the foregoing description tconnection with the accompanying it is thought that the construction and open ation or the invention will he cl arly nnden stood. and therefore more extended ere planation has been omitted. 5mg;

What isclaimed is: i 1. A portable reciprocating" savvigznachine comprising a frame, a motor support ed upon said frame and having a horizontal driving shaft, a yoke fnlernmed upon said ga shaft. a driven shaft jonrnalcd in volie rocking frame supported upon said driven shaft for rocking in a. vertical planeconnections between the driving and driven shafts! a crank shaft v,rtically'jonrnaled in the rocking frame, guide frame supported by said crank shaft, z'nide rod mounted in said guide frame and having" connection with the crank shaft for operation thereby, a saw blade connected wit the outer end of said *1 1i}; guide rod and adjustable about a longittdinal axis, means for adjusting the rocking frame means for adjusting the yoke, meai'zs for swingin the guide framegand reversing connections oetiveen the last-nained means we and the driven, shaft. 2. A portable reciprocating sawing ma chin'eicom 'irising a frame, motor supported upon said frame and having a horizontal, driving shaftw svelte fulcrumed upon said shaft a driven shaft ionrnaled in said yolie, a rocking frame supported upon said driven shaft for rocking in a vertical plane, con nections between the driving and driven shafts, a crank shat'tverticallv journaled in the rocking frame, a guide frame supported by said crank shax't. a guide rod mounted in said guide frame and having connectlon with the crank shaft for operation thereby, a saw blade connected with the outer end of said means for swinging the guide frame, re- 10 versing connections between the last-named means and the ciri'ven shaft, said means for swlngmg the guide "frame being mennted on the rocking frame.

In *testimony wheree'l? I afiix my signature 1n presence of two wiinesses.
